IMPROVEMENT IN DOOR AND GATE FASTENERS.

Specification forming part of Letters Patent No. 186,337, dated J annary16, 1877; application tiled December 15, 1876.

To all whom it may concern Be it known that I, JASON Genes, of Olyde, inthe county of Sandusky and State of Ohio, have invented certain new anduseful Improvements in Door or Gate Fasteners; and I do hereby declarethe following to be a full. clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, ref- .of parts hereinafter more fullydescribed and definately claimed.

Referring to the drawings, Figure 1 is a view in elevation of the innerface of a door provided with my locking attachment. Fig. 2 is a side oredge view with the door in broken section.

. A represents the interior face side of a single door, supported andworking in the frame B. Secured to the horizontal central cleat O is.the segmental lever button or cam D, which rotates in an arc of a circlehaving its plane parallel to the door. The pivot E passes through thedoor at right angles to same, and through the cleat 0, its outer endprovided with the handle F, and its inner extremity bent at an angle ofninety degrees,

soas to form the arm 6, which connect; with the button or cam D at theextremity of the latter opposite to that of its connection with thehorizontal connecting-link G. This part D has a twofold action-one as alever to draw out the toggle-joint by means of the connecting-lever, anda second action as a camfastener to butt against the toggle-joint'whenthe latter is in vertical line, and lock same in place. This link G ispivoted to the lower portion of the upper arm H of the toggle-levers J.The opposite end of the arm moves in and out of the mortise cut in thelower face of the upper sill of the doorframe, while the arm is pivotedto the upper cleat G of the door. The lower arm H of the toggle-leversis not fixedly pivoted to the door, as is the upper arm, but is madewith an elongated slot, h, parallel with its lon'ger dimension. Withinabout this bolt.- The lower extremity of this arm H engages in themortise cut in the upper face of the lower sill of the door-frame, whileits opposite extremity is hinged to the correspondingly lower connectingend of the upper arm H, though it is evident that the toggle-leverjointmay be by a swivel or pivot connection instead of the hinge-joint shownin the drawings. So, too, instead of tremortices in the sills of theframe, cleats may be secured to same, and thus form engagement-lugs forthe toggles, in lieu of the recesses.

A horizontal arm may be attached to the levers, to aid in looking orunlocking same from the interior; and it is apparent that double doorsmay be secured by my improve ment by having the sectional doors meet ina tongue and groove lock, or by having the half-door, provided with myimprovement, made with an overlapping cleat, which will bind the secondhalf in place.

So, too, my invention may be applied to gates, to window-sashes, andother analogous uses, the drawing representing it upon a single door,only as an illustration of its operation.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The fastener for doors, gates, &;c.., consisting in the combination,with the segmental lever button or cam D, and horizontal connecting-linkG, of the toggle-levers H H, one arm of which is pivoted, and the otherloosely working upon the face of the door or gate, substantially asdescribed.

In testimony that I claim the foregoing I have hereunto set my hand this6th day of December, 1876.
